In the chapter where you must find Capt. Keyes in the swamp, there is a secret area you can access right from the beginning.

When Foe Hammer says “The Last transmission from the captain’s drop ship was from this area. That was over twelve hours ago.” immediately start pressing your grenade throw button. Whatever you do, DON’T MOVE! After a few seconds, the drop ship will take back off, and you’ll still be in it. It flies for about 20 seconds then crashes. Press X to exit the drop ship.

Now walk directly away from the ship until you reach a clearing. Head towards the center and out of the fog you’ll see a lone marine standing there! He won’t move or say anything, unless you shoot him in the foot w/ your pistol.

JESSICA AND SPEED

Hint: Top of Truth and Reconciliation

Play on co-op, go to the gravity lift, kill all aliens, when you are done don’t go onto the gravity lift. Go to the upper left side to the single tree that is between a big boulder and a little boulder. Have your partner jump on the big boulder then jump on your partners head and on to the tree. Get high as you can in the tree, then keep killing your partner & turning until they re-spawn on top of your head. Then jump on top of the ledge and kill your partner to pop them up next to you.

Hint: Hidden Music

In assault on the control room near the end of the level on the rock road there will be a banshee steal the banshee and look behind you. if you look up you will see 3 sniper spots a bottom, middle, and top go to the middle one with the banshee land carefully and go to the right side and look at the blue light wait a while and you will hear a hidden track.

Easter Egg: Rex

On the last level the Maw, on the last checkpoint, when you go off the big jump onto the small bridge, drive the warthog so a quarter of it is off the bridge. Jump on top of the warthog and jump on top of the wall on either side (the one closest to you) and follow it up to an upper, smaller bridge. There are two hall ways and go in the one with blood in it. Look to the right and you will find the name Rex written in blood.

Hint: Attack On The Control Room Glitch

When you are going back through the “Attack On The Control Room” stage, your objective is to destroy all the generators. The moment you or your partner gets close to the last generator, the flood will kill you.

Instead, exploit the co-op system to your advantage. Notice that on co-op, when one of you is further ahead then the other player, the lagging player is warped ahead. At the hallway before the last generator, spend a moment and practice finding the warp spot, now when you’re sure you’ve located this spot have one player stand a step away from the spot that will cause the other player to warp.

Have the player that will warp go deactivate the last generator. Now as soon as the surge occurs, have the player in the hallway cause the warp and both players can leave relatively unscathed.

keitarou

Easter Egg: Megg

‘The Megg’ is one of the hardest easter eggs in Halo. After all once you see the Megg, its game over. Start a game on the Pillar of Autumn while on legendary difficulty. Jump on the cryo tube Master Chief comes out of. Jump on the shield recharger thing. Then, jump on the walkway. You’ll see some barrels. Jump on the top one. Wait for that guy that woke you up to die, then jump down. Get to the captain and shoot him. As soon as Cortana says, ‘rampant’, find the door the invincible marines came out of. If you can get past them, another door will open. The Marines can’t get you while you’re in here. Look up at the ‘M’ made out of bullets. After you see it you’re trapped and the marines now can kill you. Like I said once you see the Megg, you die.

Kevin McCormack

Hint: Falling without losing life

When falling from high distances your shield or is depleted when you hit the ground. If you hold the crouch button shortly before you hit the ground, you will not be affected in any way. This is very helpful when playing in multiplayer on levels like Hang ’em High or Prisoner. It has to be timed right though.

Slava Nossar

Hint: More Guns On The Pillar of Autumn

On the level “The Pillar of Autumn” on Easy difficulty, get to Captain Keyes as quickly as possible. When he hands you his pistol run out to the bridge and down the corridor where you load the pistol. If the glitch is done correctly, you shouldn’t load the pistol, and the 3 Grunts shouldn’t be at the end of the corridor.

Continue and pick up the Assault Rifle from the dead marine’s body lying in the doorway then kill the Elites and Grunts and pick up a Plasma Pistol or Plasma Rifle. Go back to the corridor where you were supposed to load the pistol and keep back-tracking. Eventually, you should load the pistol and the 3 Grunts at the end of the corridor should appear. You will now have the pistol, the Assault Rifle and the Plasma Pistol/Rifle.

david

Hint: Easier Play on All Difficulties

Play a game on Co-Op mode and have one the players stay back, out of range of combat. With the other player, progress through the level and engage in combat. If that player dies he will be instantly teleported back to the second player that is just standing around in a safe spot.

david

Hint: Defeat Hunter Enemies

Equip the pistol and go behind a Hunter enemy. You’ll see an orange spot on their back–hit the orange spot once and the Hunter will die.

dleit1014

Hint: Stealthiest Cloak

During multi player, when you get a cloak item and turn invisible you can do things to make yourself even less visible. The slower you move the harder it is for enemies to spot you. As well, if radars are turned on, stand completely still and you will not show up on enemy motion trackers. Perfect stealth.

steph_m9

Hint: Assault on the Control Room Shortcut Bug

When on “Assault on the Control Room”, there is a glitch to get through final door easily. Comandeer a Ghost or Banshee and fly slowly beside the door. Jump out of the vehicle in the direction of the door. If done correctly, you should be able to get pushed through the door by the dismount animation.

Nox

Hint: Accurate Assault Rifle

When playing with the Assault Rifle, the most accurate way to kill a enemy is with the three-round burst. To do this, just repeaditly tap the fire button. It should give a series of short blasts that come in handy when low on ammo, and offer more accuracy compared to just holding the fire trigger.

SquallyL

Hint: Silent Cartographer Shorcut – Squally’s Jump

In “The Silent Cartographer” there is a sizeable shortcut. It involves a large jump which can easliy kill you, but, with an Overshield, saves you some time.

First off, when you battle at the entrance to the main building on the island (the one where the door becomes locked shut), make sure to leave the nearby Overshield. After you have unlocked the door, return, and still do not use the Overshield. Kill the Jackals and hunters, then finally grab the Overshield. From there, enter the base, and hang a right to the structure jutting out from the wall. Here you can see each of the levels of the compound. Take good aim, and jump to the second lowest level. If done right, you will lose all of your Overshield, but you will land on the level above the Silent Cartographer. From here, peer over the ledge where the edge of the platform changes direction. below you is another Overhield. Simply drop down onto the Overshield, and not only will you still be alive, but your shields will be at 300% once again. Turn around you’ll be at the Silent Cartographer!

Dipto

Hint: Always Have Ghost in Assault on the Control Room

Right after you have to abondon the tank, take a Ghost and go next to the door that you need to in order to finish the level. You’ll find that the door won’t open while on the Ghost, so get off your Ghost and the door will open. Before it closes again, get back on your Ghost and go through.

Jason Lessmann

Hint: One Hit Elite Death

Have you ever wondered if it is possible to kill an Elite easily? When you come to an Elite pacing around the room, time how fast he paces by hiding behind a shield or a glass window, stay at a safe distance, or just hide behind a corner. Once you are sure you know when he will turn around, run up behind him and use the melee attack to bash the Elite on the back, instantly klling him (note that if you did not do it correctly, it will turn around and attack you). This comes in handy alot on “Attack on the Control Room” and on Legendary Difficulty.

DUKES

Easter Egg: Random Bull

Go to create a new account and type in .fortune for a name. As soon as the name is completed, a random message will appear on the screen. Re-enter the name for another message.

onnzcheez

Hint: Get a Ghost Through the Broken Blast Door

During the Two Betrayals level, the Master Chief comes upon a broken blast door and is “forced” to abandon his Ghost and face the Flood on foot. To get the Ghost through the door, line it up backwards with the hole in the door; allow the tail to stick out slightly through the hole. Leave it there. Now go back and get the Warthog, and use the Warthog to ram the Ghost through the crack. Hit it at a 45 degree angle to wedge it through.

Cheat: Refill Ammo Glitch

When using human weapons, you can reload them and not waste your ammo supply by starting the reload sequence and then immediately swapping it for another weapon that’s on the floor. Wait for the reloading sound to finish and then pick up your weapon, and you will see that it has reloaded without using your reserved ammo.

Hint: Double Beat Trick

Everybody knows that melee attacking someone can do massive amounts of damage. This double beat trick can be handy, especially if you have plasma grenades. Beat once, and right afterwards, throw a grenade and press X again to beat. You should beat twice in a row very quickly and throw a grenade.

Hint: On Top Of The World

On the Silent Cartographer level, go anywhere where there is an overshield, and bring a warthog with you. It’s best to do this in co-op because it’s easier to collect the grenades and “initiate launch-off”. Get as many grenades as you can, and have your partner kill you, and vice-versa to get the grenades into one big pile. (Make sure this is *near* an overshield.) Drive the warthog onto the grenades and try to position it to where it would fly up on top of the level. Before you do anything else, make sure you get a checkpoint. Have your buddy pick up a grenade and toss it under the warthog, and RIGHT as he throws it, pick up the overshield and get into the warthog quick. If you get into the warthog while the overshield is charging, you should get blasted upward unharmed. You should reach the top of the level. If not, reposition the warthog, or get more grenades. When you’re up there, kill your friend with the plasma pistol from long range, and he should appear up there with you. Have fun!

Hint: Early Banshee Trick

In “Assault on the Control Room,” you can get a banshee shortly after the tank. Take the sniper rifle and the rocket launcher. Clear the enemies, and then go to the boulder on the right side of the tunnel. Look up and you will see a rock bridge. Now, while still looking up, start moving forward until you see a platform coming out of the wall. Zoom in with the sniper rifle to the center of the platform, and then without moving change to the launcher and fire. A banshee will

Hint: Assault Banshee Trick

Get the banshee and fly until you get to Canyon B, where a covenant dropship comes down with two ghosts on it. Go up to the top of the center spire and take the other banshee. (If you are playing on co-op mode, push the other banshee off the cliff for your partner to use.) Destroy all remaining forces in the area, then fly through the tunnel to the area where you normally have to leave the tank. Save the marines and fly your banshee over the brown building that has the pillars at its base. Kill the covenant, then instead of going through the door, fly up to the bridges overhead. One bridge will have two green doors. Go through either door. Now there will be no enemies, and there will be all vehicles except mortar tanks at your disposal. This trick can help a little on Legendary mode.

WARNING: You may need to restart this stage if you pursue this easter egg.

In the last level of Halo, you’ll arrive at a second grouping of tunnels after the dropship pick up goes awry.

Take the first tunnel on your right and there should be a fork leading to a dead-end half way through. If you head partly that way, you can hear a grunt talking about something phenomenonally droll.

Hint: Clear Alien Drop Parties

When facing a drop ship, aim at the hatch that the enemies will come out of while the ship is descending. Your crosshair will turn red when you target an enemy (inside the dropship). This means you can shoot the enemies in the ship while it is still trying to land. You can get rid of a lot of enemies before the dropship deposits its soldiers, making the fight easier later on!

Infinite Spartan laser in Halo missionUse the following trick to get a Spartan laser with unlimited ammunition in the “Halo” mission. Play through the level until you meet up with Sergeant Johnson. Shoot him until he falls down and drops the Spartan laser. Quickly pick it up, and shoot it at him. Keep shooting him until he kills you. When you respawn, knock him down again, and pick up his laser. He should get back up with another laser on his back. When he does, shoot him down again, and pick up the new gun he drops. This laser should now have unlimited Spartan ammunition. This makes it easier to destroy the Guilty Spark 343. -From: Camuel

KatanaSuccessfully complete all achievements (1000/1000) and find all Skulls to unlock the Katana.

Bonus downloadable contentSuccessfully complete the game on the Legendary difficulty to get bonus pictures and a “Making of” video from Xbox Live.

Alternate endingsThere are three endings. The first ending is shown when the game is successfully completed on the Easy, Normal, or Heroic difficulty setting. The second ending is shown when the game is successfully completed on the Legendary difficulty setting. The third ending is shown when the game is successfully completed on the Legendary difficulty setting with all Skulls activated.

Easier Legendary modeIf you are playing alone on the Legendary difficulty setting, turn on an idle second player to stay behind. If you die, you will respawn instead of restarting.

Super fast Spartan laser fireIn Forge mode, get a Spartan laser. Charge it until it is almost about to fire. Before you fire, turn into the Monitor. Fly around until you find a target. Before you turn back into a human, hold RT to fire the Spartan laser almost instantly (if done correctly). You can use the Monitor’s aimer to aim the laser.

Smarter respawningWhen playing in Co-op mode on the Legendary difficulty setting, it is best to have one player keep their distance from the enemy at all times. By doing this, if the rest of the players die, they will respawn around the player that is farther back, rather than having to restart at the checkpoint.

Preventing lagTo clear the hard drive cache and prevent lag in Solo and Multiplayer mode, when starting the game, hold A + Up. Select “Yes” when you are asked if you want to clear the cache.

Skull locationsYou can only collect Skulls on the Normal, Heroic, and Legendary difficulty setting. You must start from the beginning of the mission. You will not be able to see the Skulls if you load from a checkpoint, unless doing so after dieing. In Co-op mode, as soon as one player picks the Skull up, all players will receive the achievement if there is one. Not all Skulls earn an achievement; only nine of them do. To use Skulls, press X at the lobby screen. This will give you a bonus multiplier for Co-op mode and go towards earning the Guerrilla, Demon, etc. achievements.

Black Eye Skull: At the start of the “Crow’s Nest” mission, without moving anything, you can see a huge pipe above you. Walk up the stairs, then up the next set. Turn to your left and jump up on the shelf unit. Jump to the red cross beam, then up onto the pipe. Then, just walk to the end. Walk over the Black Eye Skull to collect it. You do not have to pick this Skull up, it does it automatically. The Skull description reads “Bash your way to better health.” When this Skull is active, your shield will instantly charge when you use melee attacks, and will not auto-recharge anymore.

Blind Skull: In the “Sierra 117” mission, when you get to the area where you see the Phantom overhead (one of the marines will point it out), jump over the rocks, and keep following the path on the right. When you get to the cliff, there will be a rock over the side. The Skull is on the end of the rock. The Skull description reads “Shoot from the hip.” Note: This Skull has to be activated before you start a campaign map.

Catch Skull: In “The Storm” mission, go to where the first anti-air Wraith tank is located. There is a large gray cylinder in the that area on the ground on the far side from where you enter. The Skull is on the top of the silo. To get up there, perform a grenade jump off a Warthog or use a vehicle to push a large crate to the side of it; jump on the crate, then the silo. Note: Do not destroy the Wraith near the door or the Skull will disappear. The Skull description reads “Pull pin. Count to three. Throw.” When this Skull is active, every NPC will carry two grenades and throws them often.

Alternately, take a Warthog, and park the front of it next to the cylinder. Take out a grenade (plasma recommended), and throw it at the front of the Warthog. Jump at the correct moment (usually as soon as you throw it) to get a little extra boost to your jump to get to the top to reach the Skull. This may require a few attempts.

Alternately, play in Co-op mode. Have a partner stand beside the building the Skull is on. Jump on top of them, then have them jump. At the peak of their jump, jump off of them. You will land next to the Skull. Collect it, then drop down to allow everyone else to get it.

Cowbell Skull: In “The Ark” mission, pick up a Grav Lift from the small building near where you fight the Scarab. Then, proceed through the level until you reach the second sloping hallway (stairway). You should see some partitioned risers (platforms) halfway down. The Skull is on the top level. Throw the Grav Lift on the right side of the hall so it lands on the fourth little green dot from the door. Then, run, jump, and use the Grav Lift to propel you to the top. You should reach a checkpoint just as you enter the room, so if you miss you can try again. When this Skull is active, explosive force is increased.

Famine Skull: In “The Ark” mission, when you first go into the valley to the right after the wrecked Phantom, look to your left to see a huge boulder. Use a Ghost to get to the side of the boulder that is closest to the bridge overhead. It is easy to pilot the Ghost up the side of the wall using the thrust. To get the Skull, pilot two Ghosts up the wall to the top of the bridge and stack them on top of one another next to the beam where the Skull is placed. Then, jump from the top of the Ghosts towards the Skull and land on the beam. The Skull description reads “Trust us. Bring a magazine.” When this Skull is active, dropped weapons will have very little ammunition compared to normal.

Use the following trick instead of trying to get a Ghost to the Famine Skull or risking your life with a grenade. Instead of going straight to it, go the way you do later in the level with the tank. Kill all the enemies or until one drops a deployable cover. Go the way you would have. When you get over the hill, destroy the Ghosts. Go under the bridge. You will see a big rock with a pathway leading up. Follow it. When you get to the top, turn to your right. It will not have a dirt ramp, but a wall. Walk up to it. Notice the small ledge. Jump up, and walk all the way to the right. Deploy the cover so that it lands about halfway down to where the bridge slopes. Do not throw too far or it go over the ledge. Jump on top of the cover. Jump up to the narrow ledge to get the Skull. Note: There is more than one way to jump from cover to ledge; try a few if you miss.

Fog Skull: In the “Floodgate” mission, as you are walking down from the anti-air gun you destroyed in the previous mission, there will be a ramp (next to a missile launcher). Around this ramp, there is a checkpoint. At this point, you should also hear a marine yelling, “There! Over There!”. Look up and to the right, directly at the roof of the building next to the missile launcher. There is a Flood form (not to be mistaken with the two other Flood forms jumping in front of you), which is holding the Skull. Kill him before he jumps, and he will drop the Skull down to the ground where you can retrieve it. Note: Correct timing is required because if you kill him too early, the Skull will get stuck on the roof. The Skull description reads “You’ll miss those eyes in the back of your head.” When this Skull is active, your motion sensor disappears.

Grunt Birthday Party Skull: In the “Crow’s Nest” mission, immediately after the first objective, while en route to the barracks, you will fall down to a pipe. Go to the end of that pipe, then look over the edge to find a small space a few feet below. Drop over, then quickly pull back to land under the floor you dropped from. The Skull is at the end of this area. When this Skull is active, it makes Grunts explode in confetti when they are headshot. There will also be some cheering, like a birthday party.

Iron Skull: In the “Sierra 117” mission, after freeing Johnson and killing all the Covenant that come in the Phantoms, walk to the Pelican that arrives to pick you up. Face the cargo bay, but instead of going in, turn left and follow the path. Once you hit the wall, jump up to your right to eventually reach a walkway. Walk all the way to the end. Take a left, then a right. At the end of this, a little bit to the right is a dark corner. Press Up to turn your light on and you should see the Skull. If you cannot see it, you are probably standing on it. The Skull description reads “Death carries a heavy price…”. When this Skull is active, instead of losing 25 points when you die, you will lose 75.

IWHBYD Skull: In “The Covenant” mission, go to the last tower. Before you get to the Prophet of Truth, there are a series of bridges with Halos. Do not jump through any yet. First, kill the Prophet of Truth, and defeat the bridges of enemies. Then, jump through the Halos in this order, with “1” being at the entrance and “7” being the end near where the Prophet of Truth was located: 4, 6, 5, 4, 5, 3, 4. Alternately, jump through the Halos in the following order: 4, 5, 6, 5, 7, 6, 5, 4, 1, 2, 3, 2, 7, 2, 1, 3, 4, 6, 7, 5, 4, 5, 3, 4. This is much easier in Co-op mode with three or four people. This is the Halo theme if it was played on a phone by dialing the numbers. If done correctly, the Halos will start flashing, and the Skull will appear near the Prophet’s ramp. If the Halos do not flash, try again. The Skull description reads “But the dog beat me over the fence.” When this Skull is active, there is bonus dialogue throughout the game. IWHBYD stands for “I Would Have Been Your Daddy”, which is a level chapter from the original Halo. -From: crimsontwist

Mythic Skull: In the “Halo” mission, follow the normal path until you reach a cave. Follow the right wall until it branches off into a small path. At the end of this path is some rubble, and in front is the Skull. The Skull description reads “Coverage under the Covenant health plan.” When this Skull is active, you will get a 3x score multiplier for all kills.

Thunderstorm Skull: In “The Covenant” mission, after you shut down the first tower and get access to the Hornet, fly to the second tower (the one the Arbiter shut down). While walking up the stairs, go to the middle part that connects both, and there should be stairs leading up to a platform where the Skull is. The Skull description reads “Field promotions for everyone!” When this Skull is active, enemies will be much stronger.

Tilt Skull: In the “Cortana” mission, when in the circular type room with all the Flood, look for a small structure piece next to two archways. Jump on top if it, then go up on the rocks to the top left. Turn left and jump up again, then turn 180 degrees and jump to the rocks across from you. Then, follow the rock sticking out and leading up on top of the original circular room. The Skull is in a pool of blood. The Skull description reads “What was once resistant is now immunity.” When this Skull is active, enemies will have different body parts that are resistance to certain bullet types.

Tough Luck Skull: In the “Tsavo Highway” mission, once you get past the part where you are forced to leave your vehicle, you will go through a tunnel and onto an open freeway. Immediately after coming out of the tunnel, you will see a huge pipe with two yellow ladders. Climb the second ladder. You should see a Regenerator power-up. Proceed to your right onto a small platform ledge where the yellow chain link fence is located. Jump onto that ledge, crossing over the fence. Directly behind you should be a large column that is holding up the giant pipe you were just on. Below that is a walkway. Fall off the ledge onto the walkway. Walk to the end of that. You should see a hidden ledge with the Skull on it. A few attempts may be requires to jump across. The Skull description reads “Your foes always make every saving throw.”

Orbital Skull: Go to where there are two roadblocks where you have to jump. The Skull is on top of the structure on the right.

Sandbox Skull: Fly towards the sunset, and turn around to find the Skull.

Terminal locationsThe following is a list of all seven Terminal locations. To accomplish the “Marathon Man” achievement, when you find each Terminal, press RB to view the journal.

Weapon descriptions

Assault rifle: This is a very handy weapon to fight all enemies with, but not vehicles. It is useful against both Covenant and Flood and is available throughout the game.

Pistol/Magnum: This is a very powerful dual-wielding gun that has high firing power. The new pistol no longer has a small zoom and has very little bullets. It is useful against both Covenant and Flood.

SMG: This is as powerful as in Halo 2. It has been upgraded with higher firing power and has a recoil. It is useful against both Covenant and Flood but can be difficult to find. It can be dual wielded.

Battle rifle: This is a powerful burst-firing rifle that has high damage and high accuracy. It is better against Covenant than Flood. It is useful for sniping.

Shotgun: This is a low ranged but powerful weapon. It can hold small amount of ammunition but can fire in mid-reload. It is useful against both Covenant and Flood but is far more efficient when used on the Flood.

Sniper rifle: This is an extremely long-ranged rifle that can fire four shots in one round. This is the main weapon for sniping and usually takes two shots to kill in the torso.

Rocket launcher: This is an extremely high damage weapon that is good for taking out powerful opponents and vehicles. It is also useful against groups of enemies. It has splash damage. Be careful as it can also be hazardous to yourself.

Spartan laser: This is the most powerful weapon in the game but requires a long charged wait. It is useful for killing vehicles and powerful enemies. It is vital to kill the Monitor.

Plasma rifle: This is a powerful weapon that is great against the Flood. You can dual-wield them, but they will overheat if fired for too long.

Plasma pistol: One fully powered shot can take out your shield. A powerful but difficult weapon to use. It can be dual-wielded. It is useful because of its high range and high attack speed. It is better against Covenant.

Brute spiker: This is a Brute weapon that is commonly used throughout the game. It has a medium-sized clip and can be dual-wielded. It is more powerful against Covenant.

Needler: This can no longer be dual-wielded but is much more powerful. It can now explode with four needles. It is useful against a group and powerful opponents.

Carbine: This is a Covenant version of a battle rifle. It is very useful for sniping and in close combat. It fires single shots and has an average round. It is commonly used by Jackals.

Brute shot: This is a less powerful splash weapon that is useful for taking out groups or vehicles. It has a high range and is very common throughout the game.

Beam rifle: This is a Covenant sniper-rifle. It does not require clips but cannot be fired repeatedly due to overheating. It has high range and is powerful against Brutes.

Energy sword: This is a melee weapon that is extremely powerful against one opponent, usually resulting in a one-hit kill. It is useful against both Covenant and Flood. It has a small rush towards the target before striking.

Gravity hammer: This is a rare and powerful melee weapon. It is only used by extremely powerful Brutes. It can take out groups and can push opponents away. It has a tiny rush when attacking.

Frag grenade: This is a powerful and dangerous grenade that has the highest kill-radius. It has a bounce that can make killing opponents difficult.

Plasma grenade: This is a weaker grenade that can stick to opponents and detonate, killing those around it. It sticks only to opponents.

Spike grenade: This is a less powerful but lethal version of the plasma grenade. When detonating, it sends spikes shooting in all directions. It can stick to both opponents and vehicles.

Firebomb grenade: This explodes on impact spreading flames around the area. It has a burning effect that is good against Flood more than Covenant but can spread.

Recharge shields quickerIf your shields are down in Forge mode, press Up and they will recharge.

Reload quickerIf you are a Spartan or Elite and your ammunition is low, press Up again while reloading to instantly reload.

Melee fasterTo melee quicker, press B, then press Y(2), B rapidly.

Stay zoomed inIf you are zoomed in as a Spartan or Elite and turn into the Monitor, press Up to turn back into your character and still be zoomed.

CrouchingTo crouch, click and hold the Left Analog-stick. While crouched, you will not appear on motion-sensors. This is helpful in Multiplayer mode when you do not want the other team to find out where you are.

Play as the OracleAt the Forge lobby, press Up to turn into the Oracle. You can pick up items by pressing A when you see a green hand.

Exploding grenadesThrow a grenade in the air, and shoot it with a sniper rifle.

Defeating FloodWhen you kill any Flood that can come back to life by the infection forms, hit the body and it should break apart. This saves ammunition.

Defeating WraithsTo easily kill a Wraith and save time and ammunition, aim at the little circle on its back. It only takes approximately five to ten shots to kill it this way.

Illegal service tagsIf you go to “Appearance” and try to change your service tag to “I17” (Master Chief’s number is 117), the game will not allow it. It will say that the tag is reserved for use by the UNSC.

If you try to use “A55” as your service tag, you will be told that it cannot be used under UNCS regulations and rules.

Driving vehicles through invisible wallsIn certain levels in Campaign mode, you may want to take your vehicle through most of the level. However, there are invisible walls that keep the vehicle from moving past where it is needed. To pass through this, drive your vehicle through the doorway, gate, tunnel, etc. where the invisible wall is located. Just before you go through it, jump out and let the vehicle pass through the wall. This allows you to take the vehicle through the rest of the level if desired.

Go under map in Construct multiplayer mapTo do this trick, you must be in Forge mode. Make sure you sell a respawn point before doing this glitch. Start out as the Oracle. Go down the pink Grav Lift by using your boost (press LT). There should be a few holes. You cannot fit down these as the Oracle. Start boosting into one of the holes that is not a closed circle. The Oracle should go slightly lower into this hole. Make sure you keep holding boost, then turn into either Spartan or Elite. You should fall underneath the level. Make sure you drop a respawn maker on a place where you can stand so you can get back whenever desired. To confirm you are under the level, try to fly up without going through the Grav Lift. There is an invisible wall just like in the “Foundation” level in Halo 2, except on the bottom. Note: This may require a few attempts.

Dribble Skull in Crow’s Nest missionAt the beginning of the mission, grab the Skull on top of the large pipe near the ceiling before you pick up any weapons. This is easier in Co-op mode. Press RT repeatedly. This will cause Master Chief to drop the Skull, but because he has no weapons, he will immediately pick it back up, making it appear as though he is dribbling the Skull like a basketball.

Red vs. Blue reference in Crow’s Nest missionWhen you begin the mission, you will find a large roadway with many Covenant forces. You are supposed to fight your way to a door that will lead you to a room with two turbine-like objects. Instead of going through this door, follow the road all the way to the end, killing all the Covenant on the way. Once you reach the end, there will be a Marine knocking on a door wanting to get in. If you listen closely, you can hear that it is actually an excerpt from Red vs. Blue where Simmons is talking to Griff trying to get into the base. Note: There is a different message for each difficulty setting:

Easy: None

Normal: Two Marines copying Red vs. Blue.

Heroic: Simmons and Griff from Red vs. Blue.

Legendary: Church and Caboose doing a “remake” of Simmons and Griff.

Leave level boundary in Highground multiplayer mapGo down to the beach area in Forge mode, and get in a Mongoose. Have the person in the Mongoose accelerate at the barrier. Afterwards, have the Wraith boost at the back of the Mongoose from a short distance. For a brief moment the Mongoose will be past the barrier. When this happens, get out. You will then be outside of Highground. This trick works in all ocean maps.

Evil duck in Isolation multiplayer mapIn the “Isolation” multiplayer map, go to the Flood cave where the Ghost is located. Go in front of the Ghost, look up, and walk a short distance slowly. You will see a big smudge on its face, but look carefully for the duck’s body. You can partly see its face and the horns on its head. This is related to the picture in Zanzibar in Halo 2.

Leave level boundary in Isolation multiplayer mapWhile in Forge mode, get as high as possible as the Monitor. Spawn a teleporter on the ground. Then, hug any wall while still being as high as possible, and spawn another teleporter. If the teleporter beneath you is lit up as it should be, turn back into a Spartan or Elite, then go through the it. You should now be outside the level boundary.

Stretchy Master Chief in Last Resort multiplayer mapWhile in Forge mode, move to the two Mongooses next to the building on the far side of the map from the beach. Change into the Monitor, and place six or more Fusion Coils near the side of the bridge coming out of the building. Change back to Master Chief, and stand on top of the coils. Position yourself so that when they detonate you will fly into the side of the bridge. This may require a few attempts. Then, end the game. Go to the theater and watch the movie. Play the explosion slowly by tapping A quickly to pause and restart the movie. If done correctly, upon impact Master Chief will stretch out.

Flipped Elephant message in Sandtrap multiplayer mapNote: This trick is best done with two players. In the “Sandtrap” multiplayer map in Forge mode, first try to get as many pre-placed Fusion Coils and Plasma Batteries before starting. Place as many Fusion Coils and Plasma Batteries as possible in front of an Elephant, then drive into the pile. Then, shoot at the pile until it explodes. It will either just jump a little, stand up on the rear, or turn all the way around. When you get close, the message “Hold RB to flip… wait, what? How did you do that?” will appear. -From: Matthew Garriga

Get two Elephants to collide into each other. Have one flip the other over. When one is flipped over and you get close, the message “Hold RB to flip… wait, what? How did you do that?” will appear.

Drive the Elephant on a hill so it stays on it. Put exploding crates around the hanger. Blow up the crates with a plasma grenade. When it is flipped over and you get close, the message “Hold RB to flip… wait, what? How did you do that?” will appear. You can keep flipping it back and forth.

Breathing under water in Sierra 117 missionAt the end of the level, when the Pelican arrives after you have rescued Johnson, it destroys the two Covenant ships, one being above the water just outside of where Johnson is held. The other one is above the water in the place just before the Pelican lands. You can climb in. Once the Covenant ship is destroyed on the side where it picks you up, the debris that remains will float on the water. Jump onto it, and let it sink. After that, all you can do is just jump from one piece of debris to the other. If you touch the ground, you will die.

Monkeys with teddy bear in Sierra 117 missionAfter you come into contact with the snipers in the woods, follow the left rock path to find a strange family of monkeys holding a teddy bear.

Hidden area in Tsavo Highway missionAfter the part where you exit your Warthog, jump across the bridge, and kill the Brute and two Grunts that are attacking your men. Turn directly around, facing toward where you came from. Look to your left, and you will see a structure. Go up to the wall on the structure, and look to your right. There should be a pathway. Follow the path until you get on top of a bridge-like structure. There should be some dead UNSC Marines, a sniper rifle, and some other ammunition.

Crossing broken bridge with vehicles in Tsavo Highway missionWhen you reach the bridge with a Warthog or other vehicle with barriers, normally you cannot cross this area. However, back in one of the buildings before the bridge is a Grav Lift. Get it, and throw it a bit before the break in the bridge, then run the Warthog or any other vehicle over it. This will make the next area much easier, especially on the Legendary difficulty setting.

Leave level boundary in Valhalla multiplayer mapGo to the ocean barrier (the side with the ocean). Then, you and another player must get a Mongoose and Wraith. Have one player drive the Mongoose into the barrier. Keep accelerating, and have the other player get into the Wraith. Drive behind the Mongoose inside the Wraith, and use the boost. You must be close for the Mongoose to go through. Once you hit it, the other player must jump out once he or she is pass the barrier.

Easy “Used Car Salesman” achievementGo to the beginning of “The Ark” mission. Make sure you have a guest or a friend to help. Continue the mission until you reach where the crashed Pelican is found (after the first terminal). Kill the blue Brute, and grab the rocket launcher under the crashed Pelican. Continue to where the choppers are located. As you are moving, a Prowler will drive by. Ignore it because it will soon stop and abandon the Prowler leading to failure of the achievement. Another Prowler will follow. Have your guest or friend shoot it twice with a Brute Shot, then shoot at it with your rockets to get the achievement. Note: If you are by yourself, do the same thing, but instead of using a Brute Shot, throw a grenade in front of it. Then, shoot it with the rockets.
